Mounting partitions in TWRP as RW for dynamic partitioned devices
Last update : 30/4/2025 (Poco F3)
Intro
This is the (slightly) more detailed version of the 23/8/2021 blogpost where I talked about mounting partitions in TWRP as RW for dynamic partitioned phones like the X3P.
Here's hoping Android upgrades won't fuck stuff up even worse...
Guide
- Boot to TWRP (or whatever TWRP-based recovery you get), if you haven't booted already.
- In TWRP, enter Mount & tick (mount) the partitions you want to mount as RW. At this moment, the partitions will be mounted as RO, but it's fine - it'll change on the next step.
Where this Mount option depends on whatever recovery you use (unless it's LineageOS recovery or something based off that; in which case you can't), so take your time discovering this option.
- Browse to Advanced > Terminal, & enter "mount -o rw,remount [partition to modify]"
Here's some examples for the partitions :
- System : mount -o rw,remount /system_root
- System_ext : mount -o rw,remount /system_ext
- Vendor : mount -o rw,remount /vendor
- Product : mount -o rw,remount /product
- Edit your system files as you please - copy, cut, delete, whatever.
Tested devices list
Success (TWRP mounts partitions as RO, but can be mounted as RW with this guide)
- Poco F3 (skkk's TWRP 3.7.0_12‐v7.7_A12) (has toggle for mounting system partitions as rw, but didn't work on LineageOS A12L)
- Poco X3P (Nebrassy&339;s TWRP (unofficial 3.5.2 & 3.6.2_12, official 3.6.0_11 & 3.6.2_11))
- Google Pixel 3 (official TWRP 3.7.0_12)
No testing needed (due to lack of dynamic partition & TWRP mounts partitions as RW in A11 & beyond; make sure mount system partition read-only setting is unchecked if available)
- Poco F1 (pre-dynamic retrofit; confirmed with official TWRP 3.5.2-9.0, Reignz' TWRP up to 3.7.0-A12-V2 & Unofficial OrangeFox R12.1 by Tejas_Singh; though both Reignz' TWRP & Tejas_Singh's OFOX requires the command for /system_ext)
- Mi A2 (confirmed with Nebrassy's unofficial TWRP 3.5.1)
- LG V30 (unofficial TWRP 3.3.1.2 & official TWRP 3.7.0_9-0)
- OnePlus 3T (confirmed with official TWRP 3.6.2_9.0 on A11 ROMs)
- Samsung Galaxy S9 (official TWRP 3.7.0_9-0; no decryption for internal storage (/data & /sdcard); issues mounting useless /prebuilt folder unless wiped)
No testing needed (dynamic partitions)
- Poco X3N (with brigudav's TWRP)
brigudav's TWRP (at least since 3.6.2_11.1 27/8/2022 build) actually mounts partitions as rw by default. In addition, it also provides a script to mount partitions as rw.
Fail (TWRP unable to mount partition)
Untested for now
